LFTR addresses almost all of those issues that you cite. Those are "old nuclear". Proliferation (doesn't make weapons isotopes as part of its fuel cycle), 99% fuel use and breeding (even can use old "spent fuel"), low/zero meltdown risk with a simple plug that melts and liquid fuel, scalable, startable/stoppable quickly. But I agree that fission (and fusion currently) is current noncompetitive and not worth investment (aside from research) until the economies of scale that solar/wind/battery are currently undergoing stabilize or plateau.
